ALSA: control: add snd_ctl_rename()
Add a snd_ctl_rename() function that takes care of updating the control
hash entries for callers that already have the relevant struct snd_kcontrol
at hand and hold the control write lock (or simply haven't registered the
card yet).
Fixes: c27e1efb61c5 ("ALSA: control: Use xarray for faster lookups")
